Opis

In this book, I have presented a unified object caching architecture and implementation based on CORBA that can be used to cache different types of remote objects with a little modification of existing code. This approach is based on applications specific cache consistency policy, per process caching, object graph based data shipping and replication management. I have applied this architecture on applications with different types of system requirements and have made a performance comparison among them. I have demonstrated that the proposed architecture of caching results in improved performance for applications that exhibit a reasonable amount of read operations. I have then provided a 3-tier on-demand, adaptive, transparent load balancing architecture for state-full CORBA object caching system and implemented it. The proposed architecture uses a combination of interceptor and object wrapper to intercept requests at various points with minimum overhead that improves efficiency significantly. Instead of a centralized load balancer, balancing of load is performed entirely in distributed manner, which introduces the system as a fault-tolerant one.
